## What is Rotational Grazing?

Rotational grazing is a method of managing pasture land for livestock in which the animals are moved from one pasture to another on a regular basis. This allows the grasses in each pasture to regrow and provides the animals with a fresh supply of forage.

## Rotational Grazing Calculation Formula

There are several ways to calculate rotational grazing, but a common method is to use the “**stock days per acre**” formula.

To use this method, you will need to know the following information:

With this information, you can calculate the “stock days per acre” by dividing the number of animals in the herd by the number of acres in the pasture, and then multiplying that number by the number of days the animals will graze on the pasture.

This tells you that, on average, each acre of the pasture will be grazed by 20 animal days of grazing. You can use this information to determine how long to graze each pasture in your rotational grazing system.
